| description | The invention discloses a landslide time prediction method based on APSO-HMM, and the method comprises the steps: 1, carrying out the preprocessing of collected landslide full-period displacement data, and carrying out the multi-state division of the collected displacement data in a time sequence direction; step 2, training the landslide displacement data subjected to state division by using a Baum-welch algorithm, and training and constructing a landslide evolution state model APSO-HMM by using adaptive particle swarm optimization hidden Markov model parameters with disturbance factors; and step 3, the landslide evolution state model performs state decoding on the real-time acquired data by using a Viterbi algorithm to obtain a state sequence corresponding to the time sequence, and takes the current estimated state as the input of a Dijkstra algorithm, so that the possible occurrence time of the landslide is pre-judged. According to the method, the initial parameters of the hidden Markov model are optimized. |
